Mesogenic Properties of Mono, Di, Tri-functionalized Dibenzo[a,c]phenazine

We hope to achieve the goal of improving molecule nature of the liquid crystal by change the functional group or the symmetry of the molecule. In the thesis, the derivatives of dibenzophenazine are synthesized and their mesogenic properties are investigated. Polarised optical microscopy (POM) and differential scanning calorimetry (DSC) studies show all these compounds to exhibit a very wide mesophase range. These mesophases are identified as columnar hexagonal phases by X-ray diffraction (XRD).
